The mostly-morubund Hurd project is well known for what it's not: the kernel at the heart of the GNU/Linux system. But there's a long and interesting story about what it could have been, too. From Linux User magazine: "The design of the Hurd was an attempt to embody the spirit and promise of the free software movement in code." Those are mighty ambitions, and this story is as much about competing visions as competing kernels. Says Thomas Bushnell: "My first choice was to take the BSD 4.4-Lite release and make a kernel. I knew the code, I knew how to do it. It is now perfectly obvious to me that this would have succeeded splendidly and the world would be a very different place today." This is a well-written and fascinating read.

Seriously it's been used for SAAS, CPU Virtualization, outsourced file storage, web apps, and even for streaming music. It seems that anything running on the internet might be described as "running in the cloud". Hey folks, now you can talk to your friends in the cloud - it's called IRC. It's all marketing, IBM has been pioneering "clouds" for decades.

That was largely my point about TSS

Meh, I benefit from both and I couldn't care less what people want to call it. It's rare that people cannot figure it out from the context. If non-gnu userspace linux kernel distros became widely popular, then there'd be a plausible case of ambiguity, but until then I don't care about pedantry.
